An air and vapour obstacle covers the flooring of the attic room and is secured to the joists with acoustical sealant. Factory-built metal smokeshafts need to be kept from calling insulation by a minimum 75 mm (3 in.) unless or else specified by supplier or regional authorities. Mount a non-flammable radiation shield that preserves a 75-mm (3-in.) air area between the chimney and insulation.

The top of the radiation guard should additionally be a minimum of 75 mm (3 in.) higher than the level of existing or new insulation to be included. To avoid insulation from dropping behind the guard, connect a clamp-type tornado collar without sealer at the top of the radiation shield, as displayed in Figure 5-4.


A radiation barrier develops a 75 millimetre or 3-inch air space around the chimney and extends 75 millimetres or 3 inches above the attic insulation, preserving the distance from flammable materials. The top of the barrier is a storm collar clamped, not sealed, to the chimney. Above the ceiling, the air and vapour obstacle is wrapped around the drywall to contact the firestop sealant.


A collar-like ceiling trim plate is connected listed below the firestop. Common interior recessed lights are challenging to air seal efficiently and can become a fire hazard if covered with insulation.

Along the edge of shared wall surfaces.

A heavy polyethylene sheet which is caulked with acoustical sealer and stapled to the ceiling frames the electric box. An electrical cord diverts from the electrical box and down via an opening right into an interior wall surface. Openings around electrical cords are loaded with caulking or foam sealer, and caulking seals gaps along the top of the interior walls.

Attic ventilation offers a variety of objectives. It minimizes summer heat buildup, extending the life of roofing and minimizes air conditioning system tons. After air sealing, attic room air flow is your second line of defence against the water vapour that may have found its method right into the attic. It ensures a chillier, well-vented attic space much less prone to the formation of ice dams at the eaves.

Houses with actually peaked roofing systems and available attic rooms are the simplest to air vent by using the proportion of 1 to 300. This ratio refers to unhampered vent location to the protected ceiling location.


Do not use electrical exhaust fans for attic ventilation as these can draw extra air than can be provided with the soffit vents.
